It is way more than that though.

It offloads things like - Power Usage - Colo Costs - Networking (a big one) - Storage (SSD wear / HDD pools) - etc

It is a long list but what doesnt allow you do it make trade offs like spending way less but accept downtime if your switch dies etc etc.

For a staging env these are things you might want to do.

"Self hosting" may actually be referring not to hosting your own on-prem hardware, but to renting bare metal in which case the concerns around power usage, networking, etc. are offloaded to the provider.
